To /l/ IIx/1on1 it 11mg/ concer/2:

Be it knownthat l, ERNST Grone Missimcn, a subject of the German Emperor, and residingr in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Electric Signaling pparatusof which the following is a full and clear speci-- combination signals whose elements or units are in a fixed interdependence from each other, such as angular degrees, minutes and seconds, or the4 like, may he transmitted troniA a sending to a receiving,r apparaius. n this case it has so far been customary to employ electrical connections between eacn sending element, and its correspondingr receiving ele- ,ment In my ceo-pending application, Serial Number 706,368 filed of even date herewith, I have described a system of electric signaling, whereby 'auxiliary mechanical means' are employed in addition to the regular electrical connections between the corresponding sending and receiving elements. in my resent system for the sake of simplicity, I

propose to use electrical connections onlyI betweenone sending element and its corresponding receiving element, and to employ a mechanical gearing means between the several elements of the receiving as well as of the sending station. My present invention, therefore, considerably reduces the amount of electrical apparatus which heretofore has been customary with signaling systems of this kind.

My invention will loe more fully understood by reference to the accompanying diagrammatic drawing of which, v

Figure l represents an elevation of the sending apparatus;l Fig. 2 is a plan View thereof, Fig. 3 an elevation, and Fig. 4 a plan view of the receiving apparatus.

as given ahorcor the device of the se a Referring now more particularly to the drawing, 10 represents the unit dial bearing `theciphers from aero to nine-in equal distrioution upon its circumference, said dial beL ingr mounted upon the shaft il together with the armature l2 only shown in Fig. 2 diagranunatically `sol-called three-pila se liernating current delta l connection pon the saine shaft il there is mounted disk 13 i 'which carries pin 14 ata certain point of its circumference. pin il cooperates with a toot-hed wheel l5, mounted upon the t shaft 16 of the second element of the sending station. This second element, likewise,

is equippedwith a dial l? similar to the dial l0 oit the ,first element. Upon the shafts l and ll are mounted notched disks 19 and 2O respectively, which are retained .in a plurality of angular positions lay the levers 2 and 22 respectively. These levers are pivoted at their upper end and spring as shown at 23 and 'LZ-l respectively, and hear a roller at their lower end, said rollers engaging the notches oi the wheels i9 and all as clearly represented in the drawing. in this manner the dials it) and li' are retained in their proper positions to present. the digcontained upon their circumference in ainenient to eacli other and with the open-A ing 25.

The rccei ving apparatus is identical to the sending apparatus, except in that the handle 2G, which is used for manually operating the sending device, and the retaining device for the receivingI armature are omitted, The corresponding devices the receiving,n apparatus are denoniinated 'by the same n :ilA

apparatus, oy addition of indes in 10 the. dial units er" the rece' apparatus mounted with disk ia 11a. The disk carries the pin l1 meshes ivitn the toothed wheel 15a mounted upon the sh: i This sha it carries the disk 17a unica carries the tens digits at its periphery. Corre "ione i with Figs. l and 19a, '21 and 23'* are the elements comprising' the retaining mechanism for the tens disk 1?, The armature 2S which operates shaft ll is indicated only in Fig, el diagraannatically and similar to Fig'. 2 by showing athree phase alternating armature in delta connection. The broken oli portions of shafts ll and 11a indicate that these armatures are supposed to be mounted on the portions, of their'respective shafts not shown. y

The electrical connections for the present system ofeelectr'ic signaling are as follows: The arniai'tii'il 2 of the sending apparatus having afthife-phase alternating currentl winding is'oonn'ted by means known in the art, suchv 'as islipfrings and brushes (not shown here) andjconductors 27 with the corresponding elements of armature 2Sa of the receiving'fapparatus having a similar winding. The"fiells in which the armatures rotate are represented diagrammatically by coils 28 at the@- sending station and coils 29 at the receiyingt'ation. The field coils 2S and 29 are connected to a single phase-alternating current source 30 by means ot the conductors 3l and 32.- lt is well known in the art that if in such an arrangement ot' armatures and fields one armature is moved angularly (as for instance by turning handle 26 in Fig. 2 currents are set up in the armature circuits, which tend to vturn the other armature (in this case an equal angle, when such currents cease to How. ri`he operation of my present apparatus is therefore as follows: In order to transmit a desired combination signal, for instancel the number 90 having two digits, Afrom the sending to the receiving apparatus, the operator has toinove the unit eleiknent at the sending station by means ofthe handle 36 until the desired two-digit number appears underneath the opening 25. The tens dial will follow the unit-dial in sueltan order that upon one Jfull revolution of the latter,

the former will rotate one tenth of its circumference. In other words7 upon passage of the Zero of the unit-dial into the opening 25 the tens-dial will move one step forward and present the succeeding numeral underneath said opening. The motion of the ten element at the sending stationjis'not directly transmitted to the ten element of the receiving station by electrical means. On the 'trical other hand. the dial for the tens at the rc-i ceiving station. in a mechanical.way, properly follows the unit-element in entirely the saine manneras the ten-element will follow the unit element at the sending station'.

l'laving .thus described myv invention. l do not wish to confine myselt' to the precise constructions as shown and described herein, since modilications may be made thereon without departing Jfrom the. principle or sacrificing any ot' the advantages of this invention, but

I claim as new and desire to secure by Letters Patent of the {"nited States:

1. An electric signaling system ot the character described. having a sending ap'- paratus comprising a plurality of elements, capable ot' delinite'*relative motion to represent a signal. a receiving apparatus comprising a like plurality ot' elements. elecconnections between one ot' said sender elements, and the corresponding receiver element. a mechanical gearing means between the several elements of the sending apparatus and between the several elements ot the. receiving apparatus.whereby combination signals may be transmitted b y said electrical connections between only one of the sender elements and one oi the receiver elements.

2. An electric signaling system for combinatifin signals having a sending apparatus comprisingan element tor smaller units, and an element Jfor larger units which is mechanically coupled with the Jformer element, a receiving apparatus having similar elements which are correspondingly arrange/d7 and electrical connections between the sender and receiver elements denominating the smaller units.
